Bie it linowfn .that I, JOHN KOCH, of Brookline, of the county of Norfolk, and State of Massachusetts,ha ve made a'newand useful invention 'having reference Ito Furnitnrc-Dr'awers and Fasteni-n'gs .thereforgand Ido hereby declare the' samctoibe fullydescrihcd lin the following specification and represented in the accompanyingdrawings, ohwhiclfi'ff I v Figure l is'afrontfview cfa case'of vdrawers provided with myinventio-n. t

Figure 2`is a vertical'sectionthereof, 'taken through theprimary locking-apparatuso the series of drawers.

Figure is a vertical section', takenthrough the auxiliary locking-apparatus.

Figure 4 is a top, view, and l l Figure 5 is' a cross-section of'A the lower drawcr, 'thc latter being takenso as to represent the ratchet and pawl thereof.V

The purposes of the 'drmvenfastening mechanism hereinafter describedarc as follows, viz, to cause all or any number-ofthe drawers ofthe series 'to be locked when one ci' theuiis locked,"by means of its lock and key;

also, to lock a drawer by means applied-toene of -its knobs; also,l t provide such means with a mechanism by Which it maybe estop'pcd vfrom'action whenever suoli may be desirable. f

The mechanism hereinafter explained will be found to be oi'` great value for drawers of bureaus, mineralo'gical, conch-ological, or numismatical cabinets, as Vwell as variousiother articles of furniture, as, with it, all the drawers ofa series maybe locked when oneof them is locked, by a key appliedl to a-lock fixed to such drawer.

l I usually attach commor lock to the lowermost of the drawers, but this is not necessary, as it'may be applied to either ofthe others. A v

In the drawings, A B C D E represent 'tive drawers arranged within a case, -F, constructed like a conmon Abureau-case. The lowermost drawer, E, has a common lock, G, fixed-toit in the ordinary way, andso as to be locked and unlocked by-a key introducedthrough ahoy-hole', fand into the lock.- At the rear part, and to the bottom ofthe drawer, I apply a fricton-rollr, b, which, when the drawer 'is moved within its case,'rolls upon a rail or bar, c, arranged ,within the bottom, d, o i' the case, and provided with spring e, for throwing itup at its rear end. jThe said-rail or barbas an inclned'plune or cam,c, projecting from its rear part, and is vconnected with `an upright slidebolt, H, arranged in 'rear of all the drawers, and provided with a series of hooksyfff, extended f1-6m it in manner as represented in fig. 2. There is a hook to each of the drawers, except the lower onepand such hook is so arranged as to close down upon'and clasp the rear -portionq, ofthe drawer when the 'bolt H isin its lowest position, the hook, under such circumstances, operating to` lock the drawer, so as to prevvent it from being withdrawn from its case. When, however, the bolt H is inits highest position, the vhooks will be so above the drawers as to Zallow of their being opened ordlrawn out of their case.

By pushing the lower drawer'into the case and back, to plaeeuthe'roller, by its action, on the inclined plane v c, willforcc downward the bar c, which will, in turn, depress the bolt H, and simultaneouslylock all thedrawers over the lower, oneT withdrawing the said lower drawer a short' distance, thespring underneath the bar c will force upward such barfand'cause it to elevate the bolt H, so as to carry its hooks out cfengagement with 'the drawers. l

fto force its front end down below the drawer and into a notch or recess, L, madejn the bottom of the draweri There is aliixed to the under side of the lower drawers. spring-bar, I, which-is provided with a spring, K,

case F. A cord, Z, fastened to the free c iid of the spring-bar I, extends upward, and` is secured to and wound around the shank or shaftm of one ofthe knobs o.` The shank revolves freely in the drawer, and has fixed on 'it a ratchet, p, to engage with a retaining-patri, q, that isarrangcd within the drawer and against the inner side oi' its front board, r, tbc whole being as represented in thedrawings. By turning the knob, the bar I may be drawn up out of the notch, and, by means of the ratchet and pawl, such bar may be kept up out of the-notch.

YlLherirV the notch,the bar I will preventthe'draweinfrom being opened. Thus the'said bar I, audits actuating and rctaining-mechanisni, as described, become an auxiliary baiting-apparatus, which may be used with any drawer, but' when employed with the primary boitinglapparatus, as described, becomes an additional security, and prevents the drawers from being opendw-hen the key-lock may beforced.

I am aware of the subject of Patent No. 26,881, by which the drawers are locked by the action of the bolt f the lock of the upper of the series against a lever connected with along catch-bolt arranged in rca-r of the drawers, and operating with a. series of spring-.catches extended from the drawers. Therefore, I make no claim.

to such subject, the locking of the drawers by the primary locking-mechanism of my invention being effected by one of the drawers, or a roller thereof, bcingforced against an inclined plane connected with or applied to the locking-bar, so made as .to close upon-the rear parts of the drawers whilelooking them. I require no-sprngcatches to extend from the drawers for the purpose of cfs-operating with tho locking-bar in order to lock such drawers.

What, therefore, I claim as my invention, is as follows:

I claim the combination of the inclined plane or lever lc, the spring e, and the bolt H, made with hooks arranged to catch upon .the drawersas-speeit ied, such combination being arranged in manner, and so as to operate with the drawers,- as explained, and being what I term the primary or boiting or fastening-mechanism i I also claim the combination of the bar I, the spring K, the notch L, the knob o, the ratchet p, and the pawl q, as arrangedwith a drawer and its case, substantially asset forth, such combination beingpwhat I term the auxiliary fastening-mechanism.

I also claim the arrangement of the primary and en xiliary fasteningniechanisms with the series of drawers and their cese, all as described, for the purposes setforth.

` JOHN KOCH.
